Not really, this is down to consumers being fooled into switching to tiddly companies when it was pretty obvious their rates were unlikely to last long term
I think this needs knocking on the head firmly.
I don't think there are many people at all who would agree with this even industry insiders.
There was a move to increase competition because of terrible customer service and uncompetitive rates which was encouraged by government, the regulator and consumer groups.
Personally after having two really dreadful experiences with two of the big six, that not cost, would motivate me to switch to someone else (as it goes we are actually with a big six company).
Money saving experts were encouraging price comparison and were not warning about fragility of the market or sustainability of it - unlike they had for buy to let mortgages or sub prime mortgages or northern rock mortgages that effectively lend over 100% of the property in some cases.
The hindsight on this is far less of an argument than on other issues.
What is true is the government were warned on fuel security some time away and supply chain issues (particularly post brexit as this made us more vulnerable). That wasn't specifically gas but a wider problem.
I pay attention to stuff like this, and it was far from 'obvious'. The housing crash was definitely on my radar - and a cost of living crunch post brexit/covid certainly was/is on my radar (including housing crisis both in rental and ownership sectors which comes from a cost of living crunch).
I think its going to be a massive shock to people whats coming. A 20% hike in cost of living from being outside the EU was always talked about. With that compounded by covid, it could be worse than 20%.
Its frightening.
